Sam went back to the academy after the meeting with Dayus.
He is in a deep thought the whole time. He is sure that Dayus hasn't revealed the whole information, but the first soul contract they signed ensured that whatever information he got is truth. This information made him rethink his plans a bit.
So, in the second soul contract that Sam has written, he actually didn't mention much about Hub. Even though Dayus not talking about hub will definitely give him a lot of peace, Sam doesn't want peace in long term.
And Dayus' impulsive stupidity will help him a lot in the future.
Sam just wants to let the things flow on their own when it comes to Dayus and the hub. The major condition that he placed is that Dayus has to shut up about Sam and his friends as well as Dusk. He cannot talk about it, until the truth of the matter reveals itself naturally within the realm.
He also cannot help anyone or guide anyone to this matter using his bag of tricks.
